I used column A to hold the units in both sheets.
I used column B to hold the ID in both sheets.

Then I insert a new column in Grp1.

I used this formula:
=ISNUMBER(MATCH(1,(GRP2!$A$1:$A$20=A1)*(GRP2!$B$1: $B$20=B1),0))

This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)

Make the range big enough to match your data, but don't use the whole column.

And drag down the column.

If you see True, then that pair is on Grp2. False means that pair isn't on
Grp2.
